Detailed Description

Modular concept to select truth particles for the truth tree filling and efficiency calculation, this one selects detectable tracks in the ID.

This implementation of Trk::IGenParticleSelector selects generated particles which produce a detectable trace in the Inner Detector. It works by testing if production and end vertices are within Inner Detector acceptance.
